You should be able to do something with this if you require it to be done with COPY:
But, as David suggested, I'd also recommend to do an intermediate step, and load the data into a table, or pre-process the file to be how you want it.

How to use this thing in copy commandYou cannot. Either fix the content of the file or remove the arbitrary length limitation on the field (i.e., change the type to "text"). I suggest the later. You may also,copy into a temporary staging table that lacks the limit, then use insert to move the transformed data (via a select query) into the production table.David J.
